All EWE's, Flags, Pennants, K9AY's, and everything else are just small 
terminated loops. They all act like a pair of short verticals that have the 
cross-fire feedline phasing integrated into the horizontal conductor 
distance, with the vertical drops actually being the desired antennas.

You could run a wire across the bottom, except the antenna load and source 
are not symmetrically placed. This means you would have to ground the bottom 
wire to prevent the system from being negatively impacted by the 
asymmetrically of the load and source position.
